This species has been recorded parasitizing a number of hosts including Megachile relativa (Medler and Koerber 1958; Scott et al. 2000; Sheffield et al. 2008; and reared from trap nests in Burk’s Falls, ON and Pinery Prov. Park, ON (deSilva 2012),
M. centuncularis (Medler 1959; Sheffield et al. 2008), M. texana and M. frigida (Medler and Lussenhop 1968). Hobbs (1968) suggested a probable association with M. rotundata. Baker (1975) also mentions a single record from Tucson, Arizona
with a label associating a female C. moesta with M. concinna.
